More than 3.5 billion years ago, life on Earth emerged from chemical reactions. Nature invented RNA, proteins, and DNA, the core molecules of life, and created the ribosome, a molecular factory that builds proteins from instructions in the genome.

Proteins are wondrous dynamic molecules with incredible functions—from molecular engines that power motion, to photosynthetic machines that capture light and convert it to energy, scaffolding that builds the internal skeletons of cells, complex sensors that interact with the environment, and information processing systems that run the programs and operating system of life. Proteins underlie disease and health, and many life-saving medicines are proteins.

Biology is the most advanced technology that has ever been created, far beyond anything that people have engineered. The ribosome is programmable—it takes the codes of proteins in the form of RNA and builds them up from scratch—fabrication at the atomic scale. Every cell in every organism on earth has thousands to millions of these molecular factories. But even the most sophisticated computational tools created to date barely scratch the surface: biology is written in a language we don’t yet understand.

The enzyme telomerase can prevent telomere attrition from happening by extending the length of telomeres. However, in most multicellular organisms, including humans, telomerase expression is switched off, except in germ cells, some types of stem cells, and certain white blood cells. While this might play a role in preventing cancer, as most cancerous cells must switch telomerase expression back on via mutations to enable runaway replication, numerous studies have shown that increasing telomerase through TERT delays aging and increases longevity of model organisms [1].

The small molecule that could

In the lab, this is usually done by introducing genetic vectors carrying a working copy of the gene that codes TERT. It’s this gene that is switched off in somatic cells. However, gene therapies are complex and expensive, and they are just entering the medical mainstream. What if we could do the same using a small molecule?

The best supercomputers in the world have less than 50,000 GPUs, how in the world is someone going to make an AI cluster with 1.2 million GPUs?

SpaceX was back at the launch pad Sunday with an updated rocket to finish off a Starlink mission it tried to send up earlier this month.

A Falcon 9 on the Starlink 10–2 mission lifted off at 1:15 p.m. from Cape Canaveral Space Force Station’s Space Launch Complex 40 amid cloudy skies with 22 more Starlink satellites for the company’s growing internet constellation that now numbers more than 6,100 satellites in orbit.

The launch came nine days since SpaceX last attempted to knock out the mission on June 14. That attempt had a rare scrub as the countdown clock reached 0 and the rocket was ultimately brought back from the pad to allow for last week’s ASTRA 1P satellite launch to go up instead.

Best seen with the naked eye or a pair of binoculars, delicate NLCs are visible at this time of year because they’re being lit by the sun, which sets yet never gets far below the horizon.

Ideally placed in the night sky this month is M13, the “Great Globular Cluster in Hercules.” A spectacular sight in binoculars or a small telescope, the closest and the brightest globular cluster—as seen from the northern hemisphere—is about 25,000 light-years distant.

Beneath the Antarctic ice, scientists find remnants of a giant river system that flowed for thousands of miles.

Geologists digging into the massive ice sheet of West Antarctica have discovered the remains of an ancient river system that once flowed for nearly a thousand miles.

Perseverance rover recently arrived at Bright Angel, a notable site on Mars distinguished by its light-toned rocks, situated at the edge of the ancient Neretva Vallis river channel.

Last week, NASA ’s Perseverance Mars rover arrived at the long-awaited site of Bright Angel, named for being a light-toned rock that stands out in orbital data. The unique color here, as well as the surface characteristics and location on the edge of the ancient river channel Neretva Vallis, made Bright Angel a location of interest for the Mars 2020 Science Team.
